A woman in Missouri has sued the owner of a diamond ring that was found at a tanning salon after the owner failed to provide the reward that was advertised.

Bonnie Land, of St. Charles, filed the lawsuit after she was arrested when she went to return the ring several weeks after finding it - she claims she had forgotten the ring was in her pocket.

Local reports indicate that Land found the ring at The Tan Company on May 9, and forgot to leave the ring at the front desk. She realized she still had the ring after she discovered it in her jacket pocket a few weeks after. The ring is a two-carat yellow diamond surrounded by 27 smaller white diamonds.

"I'm not a thief; the worst thing I think I've ever done is speeding," Land, 34, told the St. Louis Post-Dispatch. "But this called my whole character into question."

Land went back to the salon about a month later and saw a sign with a picture of the ring offering a $3,000 reward for its return. Land contacted the ring's owner, Melisa Boucek, and the two agreed to meet the following day at the jewelry store where it had been appraised.

When Land arrived at the store police were already waiting and took Land in for questioning before charging her with theft roughly six weeks later.
